Is 73 percent oxygen 27 percent carbon the same compound has 57 percent oxygen 43 percent carbon?
If a sample of 100g of this substance were to exist, there would be 27g of C and 73g of oxygen. Multiplying by the molar mass of each of these substances we find that we have 2.25 mol C and 4.56 mol O. Finding the ratio of oxygen to carbon, we see that it is 2.03 mol O to 1 mol C. It can be concluded that this substance is CO2.
What else can I help you with?
A molecule of an organic compound has twice as many hydrogen atoms as carbon atoms and the same of oxygen atoms as carbon atoms The molecular mass of this compound is 120u What is the MolecularFormula?
The compound has a 3:6:3 ratio of carbon, hydrogen, and oxygen atoms. Given the molecular mass of 120u, we can calculate the approximate percent composition of each element. The compound is likely C3H6O3, which simplifies to CH2O.
Do the chemical formulas CO and CO2 represent the same compound?
No. CO stands for carbon monoxide and CO2 stands for carbon dioxide. CO has one carbon and one oxygen. CO2 has one carbon and two oxygens.
Do oxygen and hydrogen represent the same compound?
No. Hydrogen and oxygen are elements, not compounds. They are not the same.
Is sugar a homogeneous mixture?
No, sugar is a pure substance, not a mixture. Sugar is a compound made up of carbon, hydrogen, and oxygen atoms, and it is the same throughout, making it a homogeneous substance.
Is plain magnesium the same as magnesium stearate?
No. Magnesium stearate is a compound of magnesium, carbon, hydrogen, and oxygen. Pure magnesium is a flammable, silver-colored metal.
Why is it inaccurate to say that CO is 50 percent oxygen?
Because the mass of carbon is not the same as that of oxygen.

Are the oxygen and carbon the same compound?
No, it is not. Carbon refers to the element C, with the atomic number 6. Carbon Dioxide refers to the compound formed when one carbon atom and two oxygen atoms are bonded together through covalent bonds. -- Carbon dioxide is a molecule consisting of 1 carbon atom and 2 oxygen atoms. --
What is law described by the fact that carbon dioxide consists of 27.3 carbon and 72.7oxygen by mass?
This is described by the law of definite proportions, which states that a chemical compound will always contain the same elements in the same proportion by mass. In the case of carbon dioxide, the ratio of carbon to oxygen by mass will always be 27.3% carbon and 72.7% oxygen.
Are carbon and oxygen the same thing?
Carbon and Oxygen are different elements.
What is the number of element in a oxygen?
oxygen is represented as O. There fore it only has one element. however if it has more than one TYPE of element it is known as a compound for example CO which is carbon and oxygen (carbon monoxide). if it has a lot of the same element it is written like this O2 (two oxygen atoms) or CO2 carbon dioxide.
Do the chemical formulas CO and CO2 represent the same compound?
No. CO stands for carbon monoxide and CO2 stands for carbon dioxide. CO has one carbon and one oxygen. CO2 has one carbon and two oxygens.
Do the relative positions of sucrose in the periodic table agree with the theoretical prediction about the kind of compound these elements should form?
Yes, the relative positions of carbon, hydrogen, and oxygen in the periodic table agree with the theoretical prediction about the kind of compound they should form. Carbon and oxygen are in the same group and tend to form covalent compounds, while hydrogen typically forms compounds with other elements through ionic or covalent bonds. Sucrose, a compound made of carbon, hydrogen, and oxygen, is a covalent compound in line with these predictions.
Do oxygen and hydrogen represent the same compound?
No. Hydrogen and oxygen are elements, not compounds. They are not the same.
Is sugar a homogeneous mixture?
No, sugar is a pure substance, not a mixture. Sugar is a compound made up of carbon, hydrogen, and oxygen atoms, and it is the same throughout, making it a homogeneous substance.
Is water and carbon dioxide a compound or a element?
The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water (H2O) and salt (Sodium Chloride - NaCl). So they are both compounds
Why is carbon so abundance in living things when oxygen is the most abundance element on earth?
Actually, oxygen is just as abundant as carbon, in living things. There is no life without oxygen (oxygen is part of water, to mention one vital compound). Carbon and oxygen each have an essential role to play, and the same is true of hydrogen, nitrogen, sulfur, calcium, phosphorus, magesium, sodium, and several other elements.
